To all whom t may concern.'

lle it lrnown that l, RICHARD C. -lnooam a citizen ot the United States, residing at South Bend, in the county oi St. Joseph and State ot Indiana, have invented certain new and useful Improvements in Concrete-Wall Molds, of which the following is a specilication.

rlhe invention relates to concrete wall Inolds and has for its object to provide a device ot this character wherein wall sections having vertical columns at their ends may be formed in such a manner that .each section will be interengaged and the window openings in the sections formed around a window trarne disposed between .detachable mold sections.

A further object is to provide a wall mold i'fornied troni a pair of spaced nieinbers, one ot said members being provided with vertically disposed recesses for forming a col umn and with a detachably vertically disposed removable zneniber 'lor forming a vertically disposed recess in the colurnn. Also to provide the adjacent faces ot the inold sections with inwardly extending bevel flanges adapted to receive therebetween and engage a window traine, thereby allowing window opening to be formed with the frame therein, said bevel flanges and traine being of suiiicient width to maintain the inner 'walls oit the niold sections in spaced parallel relationto each other.

lli/'ith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set tor-th, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

ln the drawings z- Figure l is a side elevation of a cornpleted wall section, showing the mold in position for forming an adjacent interengaged wall section.

Fig. 2 is a top plan view of a formed wall section, showing the niold in position for forming an adjacent interengaged wall section.

Fig. 3 is a perspective view of one of the mold sections, showing a portion of the column of a formed wall section.

Fig. a is a perspective view of the strip `the longitudinally disposed bars l5.

used to rnalre the groove in the side oi the column.

Referring to the drawings, the ruinieral l designates a wall section having at one of its ends a vertically disposed integral coli unin 2. he coluinns 2 have their side formed with vertically disposed recesses 1:3 for the reception of the adjacent ends -l oi? the wall sections, thereby interengaging the wall section and preventing displacement oli the sections in relation to each other, Each section l, if so desired is iornied with a beveled opening 5, preferably rectangular shaped and in which opening a window traine 6 is disposed. The window :trarne 6 is preferably placed between the bevel flanges 7 of the :mold sections 8 and 9 and with which trarne said bevel flanges 7 engage thereby utilizing the trarne 6 for forniing the window opening, and at the saine time allowing the trarne to be securelyY held in the window opening 5 when the vall sertion is formed.

The inold sections 8 and 9 have Vtheir inner walls 10 and ll spaced from each other by the bevel flanges 7' and the window :trarne 6 and Vare held in spaced parallel relation to each other by said bevel flanges and frame 6. The ends or" the sections 8 and 9 are provided with vertically disposed reA cesses 1l, which recesses forro the columns 2 at the ends ot the wall sections l, the vertical recess 3 beingtorrned by the removable vertically disposed strip l2, the sides ot which are engaged by the sides i3 of the column forming flanges and is held therebetween in any suitable manner. verticallyV disposed strip 12 is oil suilicient width that the sides i3 of the column forming flanges le are in engagement with the sides of the strip l2, the inner walls 10 will be in spaced parallel relation to each other. The sides 8 and 9 are built up from boards having longitudinally disposed reinforcing bars l5 which are held in spaced relation with each other by means of vertically disposed bars 16 which are nailed or otherwise secured to l One of the ends of the bars l5 extend beyond the ends of the column forming portions of the mold sections 8 and 9 and have secured thereto horizontally disposed blocks 17, the blocks 17 of the section 8 Vabutting the blocks 17 of the section 9 and engaging the outer faces of the flanges 14 in such a manner that they form means tor additionally 4holding` the vertically disposed strip i2 against outward displacement when concrete is disposed between the mold sect-iene 8 and 9.

The ends 18 ot the mold sections 8 and 9 are provided with vertically disposed angles 19, the flanges 2O oi which are spaced from each other substantially a distance equal to the thickness of the column 2 and engage the outer faces ot said column with the ends 18 ot the mold sections in engagement withthe end tace of the column 2, in such a manner that the vertically disposed recess 3 will register with the space between the mold sections 8 or 9. l/Vlien concrete is poured between the mold sections 8 or 9 another wall section similar to the wall section l is formed with a vertically recessed column at one end and with its other end interengaged with the vertical recess 3 of the column 2 ot the wall section l which has been previously termed. y The operation is repeated as desired until a wall is formed ot the desired length.

The mold is particularly adapted tor use in constructing small houses, such tor inh stance as garages and fone story houses, however it is to be understood that houses of two or more stories may be also formed it so desired.

The mold sections 8 and 9 atter beingplaced in position as shown in Fig. 2 may .be cleated together across their tops or ends prising a pair of spaced mold sections, said.

mold sections having` their inner faces provided withV inwardly projecting window opening forming members adapted to engage opposite `faces of a window trame, one end of each mold section being provided with vertically disposed column forming recesses and a substantially centrally disposed vertical removable strip interposed between the ends of the mold sections adjacent the column forming recesses and forming means for forming a vertically disposed recess in the end tace vof a column.

2. A sectional wall forming mold comprising a pair of spaced mold sections, said meld-sections having their inner faces provided with inwardly extending beveled window opening forming members adapted to engage opposite faces of a window Jframe, said window opening forming members and the windowV trame held therebetween forming means for maintaining the mold sections in` spaced parallel relation to each other, one end ot each or ythe mold sections having a vertically disposed column forming recess, a removable strip disposed between the recessed ends of the mold sections and extending inwardly, and members carried by the opposite ends ot the mold sections for engaging opposite sides of an adjacent column and forming means for maintaining the chamber of the mold in registration with a vertically disposed recess in said adjacent column.

8. A sectional wall forming mold comprising a pair of spaced mold sections, said sections having inwardly extending members on. their adjacent faces for engaging opposite sides of a window trame for forming the wall'around said window frame,

yvertical oppositely disposed recesses at the ends of the mold sections, a vertically disposed strip disposed hetween the recessed ends of the mold section and extending inwardly, and means for maintaining the mold sections in spaced relation to each other.

In testimony whereof, I atx my signature.
